Detail point
With the function Calculate > Detail
Point, surveyed points orthogonal to a measured line can be transformed into
coordinates of the current system and the other way round. For this purpose, the
submenus Detail
Point and Transformation
on Ref.Line are available.
If a line has not yet been defined, the input dialog for the measured line
appears first of all. Here, the starting and end point numbers as well as their
local coordinates can be entered. The following rules apply to such an input:
-
If a Y-field is unoccupied, it is assumed to be 0.
- If an X-field is unoccupied, it is computed.
-
If both X-fields are unoccupied, the first is assumed to be 0 and the
second is calculated.
The local magnitudes are reduced prior to the detail point calculation.
In the submenu Detail Point you
can enter the surveyed detail points with their ordinates and abscissa.
During input of the coordinates, the point is represented in the graphic. When
the input has been confirmed with <OK>,
the dialog for saving coordinates is called up and point number and code can be
entered.
By pressing the button <Line>,
a new measured line can be defined so that a new detail point measurement can be
entered.
The function Transformation
on Measured Line calculates the detail point magnitudes of a point with
reference to a measured line. To this end, when a measured line has been
defined, it is only necessary to select a point in the graphic or enter it in
the field PtNr. The detail point
magnitudes X and Y
as well as the coordinates of the foot point are then represented in the dialog.
The result of the calculation can be protocolled by clicking the button <Print>.
A new measured line can be defined by pressing the button <Line>.
The graphic enables a visual control of
the calculations.
